Title: Apparatus for the attenuation of undesired signals in complex- electrical signals
IPC: H03C1/04
Filed: 1973-12-28
Abstract: 1446909 Stereophonic systems; testing stereophonic receivers MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 28 Dec 1973 [29 Dec 1972] 60012/73 Heading H4L Means are provided for balancing out spurious signals in a signal generator. In one arrangement described, quadraphonic signals are generated for transmitting, or for testing receivers. As shown in Fig. 2, a modulating signal is supplied via terminal 21 to a modulator 23 and a carrier wave is supplied via terminal 22. The undesired signal is assumed to be the third harmonic and the carrier is tripled in frequency and supplied to a modulator 25 receiving also the modulating signal. The output of modulator 25 is adjusted in amplitude and phase at 26 and is combined at 27 with the output of modulator 23 in the correct sense to balance out the unwanted signal, the resultant being supplied via a low pass filter 28 to the output 29. In a modification, Fig. 3 (not shown), the correcting signal is automatically controlled in accordance with components of the unwanted signal appearing in the output of 27. Quadraphonic signal generator.-The fourchannel signal to be generated consists of a main channel signal extending from 0 to 15 kHz, two orthogonal phase signals with a suppressed carrier of 38 kHz a signal with a suppressed carrier of 76 kHz and one or more pilot signals, Fig. 4 (not shown). When generated on a time division basis a series of unwanted signals are produced and particularly one centred around 114 kHz, the third harmonic of the 38 kHz subcarrier. As shown in Fig. 5, the input signals a, b, c, d, are supplied to gates 51, 52 and matrix 54 (which adds the input signals) all connected in parallel. The gate circuits are controlled by a 12-stage shift register with eight three-input OR gates 59 receiving pulses CP, Fig. 6, at a rate of 456 kHz from a generator 58. One stage of the shift register is always at 1 and the others at 0, SR denoting the number of the stage at 1 at a given time. The output of 59 is also frequencydivided at 60 and filtered at 61 to provide the 19 kHz pilot signal. The outputs of gate 52 and matrix 54 are adjusted in amplitude at 53, 55 respectively, and combined in matrix 56 with the output of gate 51 and the pilot signal. The resultant composite four channel quadraphonic signal has the unwanted third harmonic signal of the 38 kc/s. subcarrier balanced out and remaining higher frequency spurious components are removed by the low pass filter 57. The operation of gates 51, 52 is shown at G1, G2 respectively, a, b, c, d, indicating when the corresponding signals are allowed to pass and it is shown mathematically that when these signals are added the required quadraphonic signal is produced with the unwanted component removed. However the sum signal is not of the required level and this is compensated for by the output of matrix 54. In Fig. 6, PL indicates the 19 kHz pilot signal and C2<SP>1</SP> indicates the gating sequence if cancellation of the unwanted signal is by subtraction instead of addition.

Abstract: 1,176,750. Running alternators in parallel; synchronizing. SIEMENS A.G. 20 Dec., 1968 [20 Dec., 1967], No. 60849/68. Heading H2H. An electricity supply system wherein two or more alternators feed a single network, the alternators being driven by prime movers which are provided with control circuits so as to be controlled in dependence upon the frequency and power outputs of the alternators is further provided with means to ensure equal division of a common load between the alternators. Generating units A1, A2 are connected in parallel to a common bus-bar B so as to supply a load C. Each generating unit comprises an alternator F driven by a diesel engine D the fuel supply to which is controlled by a valve E which is itself controlled by the output signal from an amplifier G. The input signal to the amplifier G is derived from a transducer H which produces a signal representing the alternator r.p.m. or frequency, a device O giving a signal representing the real power output of the alternator. The signal from the device O is fed to a function generator P which produces an output signal inversely proportional to the input signal which output signal is compared with the signal from the transducer H in a comparator N. The output signal from the comparator N is used to control a motor L by way of a device M, the motor L driving a pick-up device K so as to produce a signal representing the desired characteristic of the alternator F, this latter signal being compared with the actual speed or frequency signal from the transducer H in a device J thereby controlling the amplifier G and the fuel valve E of the diesel D. In order to control the load division between the alternators F1, F2 (Fig. 2), the signals from the devices 01, 02 are fed to the function generators 31, 32 by way of variable gain amplifiers 21, 22 the gains of these amplifiers being controlled by the voltages which appear across similar impedances 61, 62 connected between the outputs of the devices 01, 02 and a common connection T. The amplifiers 21, 22 and the function generators 31, 32 preferably comprise transistors. In order to synchronize the units A1 or A2 (Fig.1) the switch S is moved to contact a and a signal representing the bus-bar frequency is fed to a terminal R. The control system then functions to control the valve E so as to bring the unit up to synchronous speed when the unit can then be switched to the bus-bar B.

Title: 2-part collet chuck
IPC: B23B31/20
Filed: 1978-07-20
Abstract: A collet chuck is formed with a collet chuck or nose part 21 releasably coupled to a collet tube part 22 which is threaded. The collet chuck part provides a ring of jaws having their flank surfaces joined to one another by resilient means e.g. a layer of elastomeric material. A compression force applied to an external frusto- conical surface 25 of the chuck part causes the jaws to be compressed independently inwards so that they can grip a workpiece located between them. The coupling device 23 provides abutting torque-transmitting surfaces on interdigitating axial projections on the two parts, the projections defining also a channel in which a retaining or coupling ring 43 is accommodated to prevent separation of the two parts when in use. Disconnection of the coupling is achieved either by removing the ring or by increasing the angle of the jaws to the chuck part axis which causes the chuck part projections to disengage from behind the coupling ring. A change-over device which can be applied to the chuck part when it is to be replaced, is operable to vary the jaws angles simultaneously. The design of the collet chuck in two disconnectable parts reduces the overall cost and size of a set of collet chuck on a lathe as the tube part does not have to be removed with the chuck part. <IMAGE>
